To all whom it may concern:

Be it known that I, CARLn'roN ELLIS, a citizen of the United States, residing at Larchmont, in the county of'Westchester and State of New York, have invented certain new and useful Improvements in Met-al- Polish, of which the following is a specification.

This invent-ion relates to a composition of matter intended for use as a metal polish and relates particularly to a non-inflammable composition comprising aheavy naphtha, such as may be obtained from petroleum or coal tar by suitable distillation and fractionation.

Many of the distillates of petroleum and coal tar such as benzol. and stove gasolene are very inflammable and when mixed with a non-inflammable liquid such as carbon tetrachlorid do not make mixtures of a sat isfactorily high flash point without the use of excessive amounts of carbon tetrachlorid. It is the object of my invention to combine the certain distillates or fractions referred to with a small quantity or modicum of carbon tetrachlorid or similar miscible non-inflammable material so as to produce a compositionnot flashing at ordinary temperatures. For this purpose I make use of the heavy naphtha fraction of coal tar known as solvent naphtha or preferably certain petroleum distillates having flash points of from say 95 to 105 or 110 F. or even higher, employing distillates which have been so thoroughly rectified that there is no Solvent naphtha 78 parts Carbon tetrachlorid 10 Amyl acetate 5 Pine oil 3 Lemon grass 1 Red oil 4 Tripoli 3O Another composition of a somewhat similar character conslsts of Petroleum distillates flashing at about 105F 80 parts Carbon tetrachlorid 10 Nitrobenzol 6 Wood turpentine 4 Silex 80 In the above composition, it will be observed that the carbon tetrachlorid is used only about'to the extent of 10% of the entire liquid components. Even less than this will suffice under some circumstances. The stearic acid or red oil is added for the purpose of securing additional detergent and polishing properties, but may be omitted if desired. The material employed in this composition should be preferably entirely free from water and I recommend thoroughly drying the abrasive powder employed before it is used.

It should be understood that I do not wish to limit my invention to the details of the above formulas and embrace in this invention those equivalents which may properly fall into the category indicated.
